I find that purchasing the bundle package is the best way to purchase ink cartridges for this printer. They are also sold separately by color but it is more cost effective to buy them as a bundle. I do a lot of printing in color and they last me about a month on average some colors obviously last longer. I love the printer also and the ease of use to change the cartridges is great turn the safety and and insert the cartridges individually you can recycle the old cartridges at staples for reward credit.

Ink arrived quickly and we were able to continue work flow without delay. We've tried off brands of ink but they do not compare with the quality of the Brother ink cartridges. The vibrant colors make the final product look professional and appealing to those we must present the paperwork to. With any presentation ease of reading is important. The clarity of the document is a plus along with ink that can be depended on to be consistent and not blotchy as some of the off brands often do.
